+# blurhash: panic on parsing crafted blurhash inputs
+
+## Impact
+The blurhash parsing code may panic due to multiple panic-guarded out-of-bounds accesses on untrusted input.
+
+In a typical deployment, this may get triggered by feeding a maliciously crafted blurhashes over the network. These may include:
+- UTF-8 compliant strings containing multi-byte UTF-8 characters
+
+## Patches
+The patches were released under version 0.2.0, which may require user intervention because of slight API churn.
